Case of warty dyskeratoma on the anterior chest: The relationship between its dermoscopic and histopathological findings

A case of post-inflammatory warty dyskeratoma of the chest: Other dermoscopic features

“…Most authors believe that cutaneous WD is derived from the hair follicle because of its closeness or clear-cut connection to pilosebaceous unit, 3,[5][6][7]9 thereby suggesting that "follicular dyskeratoma" might be a better term for this entity. 6 A study performed with human keratin antibodies, specific for cortex and inner root sheet of normal human hair, 8 and a survey carried out searching the expression of cytokeratins CK 1 , CK 5 , Ck 10 , CK 17 , CK 19 5 confirmed this hypothesis. WD arising in regions devoid of follicular structures (oral mucosa 12 and nail bed 13,14 ) may represent examples of isolated FAD secondary to a local inflammation or a neoplastic proliferation.…”

“…Dermoscopy of WD has been performed in a limited number of cases (Appendix). [16][17][18][19][20] Papules of acantholytic dyskeratotic acanthoma, acantholytic dyskeratoses, and Grover's disease display a central yellowish to brown star-like pattern overlying a pinkish homogeneous structure-less area. 16 Syringocystoadenoma papilliferum reveals a polymorphous vascular pattern on a pinkish-white background.…”

“…16 Syringocystoadenoma papilliferum reveals a polymorphous vascular pattern on a pinkish-white background. 19 Papules of Darier's disease show a centrally located yellowish/brownish area surrounded by a thin whitish halo. 17 Dermoscopy of keratoacanthoma and squamous cell carcinoma is characterized by keratin masses, white structures (white circles, white clods, and white structureless areas), and hairpin vessels.…”

Warty dyskeratoma: The relationship between its dermoscopic and histopathological findings

“…Warty dyskeratoma (WD), a benign follicular‐type tumor, was first reported by Szymanski in 1957 1 . The dermoscopic aspect of WD was described in reports between 2016 and 2020, 2–7 but the reports did not include sufficient detail. Here, we present a case of WD based on its dermoscopic appearance.…”
